HYDROCARLBON-STILL.

Specification of Letters Patent. Application filed December 4, 1906. Serial 1V0. 346,343.

Patented April 2i, 190s.

To all whom it may concern:

Be it known that I, THEODORE H. ELLIS, a citizen of the United States of America, and resident of Baltimore city, and State of Maryland, have invented certain new and useful Improvements in Hydrocarbon-Stills, of which the following is a specification.

My invention relates particularly to stills of the ty, e employed in the distillation of hydro-car ons, andhas for its object a construction of the still such that the aqueous, and light or deleterious oil va ors driven oil in the distillation, recondense in art within the still by contact with the wa s thereof, may be prevented from passing back to the residue.

, I accomplish. the purposes'of my invention by a peculiar construction within the walls of the still, by means of which all va-- pors condensing within the still are guided down and carried from. the still Without re achingthc residue.

' Having set forth the objects and. nature of my invention I will now describe the same of Fig,

in connection with the accompanying drawin s, in which Figure 1 is a view showing a central, vertical section of a still embodying my invention. Fig. 2 is a view similar to Fig. 1,

showing a dill'erent form of the'invention. Fig. 3 1s a hm'izontal sectlon on the line ,6--6

1. erring to the drawings,in Fig. 1 is shown a still 1, mounted on a suitable l'urnace 2 andconnected at 3 with the source of oil supply and at 4'with acondenser 5. The still shown is of the ty e described in m copendingapplication 0. 335,484, filed ept;

20, 1906, in which the distillationis lar'ely eli'ected by means of compressed air supp ied from tank 7 see Fig. 2 by means of pi e 8, to

a coil 9, at the bottom of the still, per or'ated,

invention. The plate 10 is annular or ex shown mounttends entirely around the still, and may have a slight deflection toward one side thereof in order that the liquid in the gutter may more readily )ass to the off-take. If the still is other than circular, the plate 10 is she )ed to accord therewith.

' P ates 34, 35 and. 36 are attached to the still above the plate 10. The plate 34 extends over the gutter formed by the late 10, the plate 35 over the plate 34 and t e plate 36 over the )late 35. By means of the arrangement shown in Fig. '1 any iluids condensed upon any of the plates 34, 35, or 36,

pass to the inside of the plate below and ultimately reach the gutter formed by the the plate 10, which, is suitably connected to condenser 13 and receptacles 14.

In Fi 2 there is shown a modification of.

my invention. As in Fig. 1, the still is provided with a lower gutter plate 18, and plates 34, 35 and 36 above the same. In Fig. 2, however, the still, is also provided with-plates, 22 and 23, forming with the wall of the still gutters, 24 and 25. Each of the gutters 19, 24 and 25, is provided with separate connection to separate condensers 13, 27 and 29. In Fig. 2 the plate 34, as in Fig. 1., extends over the gutter 19 formed by the late 10. The plate 35, however, instead of delivering to the plate 35'extends over the gutter 23. In Fig. 2, therefore, the condensed distillates from the plates 34, 35 and 36 instead of passing to a common condenser, asin Fig. 1, ass to separate condensers, whereby the distil ates may be separately recovered. Ifdesired, one or both of the con-' densers 27 and 29 may be'cut out of use.

Whereas I have shown three gutters or collecting devices, the number shown may be varied according to circumstances or desire. In fact, the numberis preferabl de termined by the nature of thematerial eing distilled, by the tem erature of the still, the pitch of the plates t 10 draft or rate of condensation and other features. If the recondensed' oil is heavy, or of considerable viscosity, and the temperature of the still is comparatively low, the recondensed fluid may adhere more tenaciously to the roof of the still, in which case a smaller number of gutters or oiftake vill be sulficient. If, however, the oil is li ht and thin, or the temperature of the stil is com aratively high the oil or water may drop rom the roof oi the of delivering to the plate 34 extendsoverthe gutter 24, and the plate 36 instead still before it reaches the bottom, and unless the-still is provided with additional plates or gutter-Ways, as shown, may drop back into the residue. It Will therefore be seen that the number and design of the gutters 0r col-' lecting devices is to be determined according to conditions of distillation and material being distilled.

Having thus described my invention What within the still, the lower edge of the top plate lying outside of the top edge'of the next plate, and the lower edge of the bottom plate over the gutter.

2. In a still, a receptacle for holding the material to be distilled; a condensing surface above the other within the still, the lower edge of each plate lying outside of the top edge of the plate next below, so thatthe inside of each )late drains onto the outside of that next be ow it; and means for draining the lower plate of the series.
